BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a water dispensing system, and moreparticularly to a heating and refrigerating water device, wherein thewater is heated and refrigerated within a single thermos container so asto simplify the structural design of the water device.

2. Description of Related Arts

Electric water dispensers are considered as one of the major homeappliances for applying hot and cold water. Generally speaking, thereare two types of electric water dispenser which are a water boiler and awater dispenser.

A conventional water boiler generally comprises an outer casing, aninner thermos container disposed in the outer casing, and a boilingdevice adapted to boil the water in the thermos container so as to keepthe water at a predetermined temperature therein. Since the boilingdevice can boil the water at a relatively high temperature, such as 100°C., to kill the bacterial in the water, tape water is safe to use as asource to fill in the thermos container. However, mineral or otherimpure substance will form as a layer on an inner wall of the thermoscontainer over a period of continuous use. In other words, the waterwill be polluted once the impure layer is formed on the thermoscontainer. In order to reduce the possibility of water pollution, theuser must clean the thermos container frequently. Therefore, most waterboilers are designed that the thermos container can be detached from theouter casing for hygiene purpose.

It is no doubt that the water boiler can minimize the microorganism inthe water by boiling the water at higher temperature and reducing thepollution of the water by cleaning the thermos container. However, thewater boiler can only provide hot water. In other words, in order torefrigerate the water, other water refrigerating device must be used.Therefore, most families employ the water boiler only at the winter timeand store it at the summer time.

In order to provide both hot water and cold water in one waterdispenser, the dispenser generally comprises a water reservoir forstoring a predetermined volume of water, a water heating device forboiling the water from the water reservoir and a water refrigeratingdevice for refrigerating the water therefrom. Accordingly, the waterboiling device comprises a first water container communicating with thewater reservoir and a boiling device for heating up the water within thefirst water container. The water refrigerating device comprises a secondcontainer communicating with the water reservoir and a refrigeratingdevice for cooling the water within the second water container.Therefore, the user is able to select the water to be either heated upor refrigerated via the water boiling device and the water refrigeratingdevice respectively.

However, the water dispenser requires two individual water containers toboil and refrigerate the water respectively such that the structuraldesign of the water dispenser is complicated so as to highly increasethe manufacturing cost of the water dispenser. In addition, each of thefirst and second water containers is a sealed container and ispermanently installed into the water dispenser such that the user is notable to remove the water containers from the water dispenser in order toclean the water containers. It is worth to mention that an impure layerwill gradually formed on an inner wall of the each of the watercontainers over a period of continuous so as to pollute the water.

According to the preferred embodiment, the thermos container 10 is madeof thermal resistance material, such as ceramics, glass, or stainlesssteel, such that the thermos container 10 can be cleaned easily, whereinthe water within the thermos container 10 is adapted to be boiled at ahigher temperature, such as 1001C, via the heating unit 21 or to berefrigerated at a lower temperature via the semi-conductor refrigeratingunit 22.

The thermos container 10, having a water chamber 11 and a top opening 12communicating with the water chamber 11, is embodied as an inner casingof the conventional water boiler, wherein a sealing cover 13 isdetachably covered at the top opening 12 to sealedly enclose the waterchamber 11 for allowing the water chamber 11 to be cleaned. In addition,the thermal container 10 further has an inner thermal insulating layer14 formed at an inner wall of the thermos container 10 for retaining thewater therewithin at a predetermined temperature.

Accordingly, the conventional water boiler generally comprises a waterdispensing unit which comprises a water pumping pipe extended into thewater chamber 11 and a water pump arranged to pump the water within thewater chamber 11 to a water outlet via the water pumping pipe. Thewater, having a predetermined volume such as 1 to 3 liters, is filledinto the water chamber 11 for being either heated up by the heating unit21 or refrigerated by the semi-conductor refrigerating unit 22. In otherwords, when the heating and refrigerating water device is incorporatedwith the conventional water boiler, the water boiler is adapted to notonly boil the water within the thermos container 10 but also refrigeratethe water therewithin.

As shown in FIG. 1, the heating unit 21 comprises an elongated heater211 electrically connected to the control circuitry 30 wherein theelongated heater 211 is substantially extended to a bottom portion ofthe water chamber 11 of the thermos container 10 for heating up thewater therewithin. Accordingly, the elongated heater 211 can be aconventional heating wire having a L-shaped supported by the sealingcover 13 to extend within the water chamber 11 of the thermos container10 by generating heat energy along the elongated heater 211.

The semi-conductor refrigerating unit 22 comprises a refrigerant member221 as a cooling source electrically connected to the control circuitry30 and a transmitting member 222 extended from the refrigerant member221 into the water chamber 11 of the thermos container 10 forrefrigerating the water therewithin.

When the current passes thecontrol circuitry 30 at one direction, the heating unit 21 is activatedfor heating up the water within the thermos container 10 while thesemi-conductor refrigerating unit 22 is remained deactivated. When thecurrent passes the control circuitry 30 at an opposed direction, thesemi-conductor refrigerating unit 22 is activated for refrigerating thewater within the thermos container 10 while the heating unit 21 isdeactivated. Therefore, by controlling the flow of current, the controlcircuitry 30 selectively controls the activations of the heating unit 21and the semi-conductor refrigerating unit 22.

Accordingly, the heating and refrigerating water device furthercomprises a temperature sensor switch 40 electrically connected to thecontrol circuitry 30 for detecting a water temperature within thethermos container 10, so as to activate the temperature controlarrangement 20 for maintaining the water within the thermos container 10at a predetermined temperature.

In other words, the water temperature within the thermos container 10 isretained at a safety temperature to prevent the water from being overboiled or over refrigerated by the heating unit 21 or the semi-conductorrefrigerating unit 22. Therefore, the heating unit 21 will heat up thewater and the semi-conductor refrigerating unit 22 will refrigerate thewater until the water temperature reaches the top and bottom temperaturelimits respectively.
